“…Similar research was performed in the region of the landfill in Sosnowiec (southern Poland). The results of contamination index determined by the Backman method based on data from the monitoring of groundwater in 2014-2019 from the municipal landfill indicate high groundwater contamination in its area (Knopek and Dąbrowska, 2021). There, the C d index was determined on the basis of the parameters that most exceed the criteria of the Regulation of the Minister of Maritime Economy and Inland Navigation of October 11, 2019, on the criteria and method of assessing the status of groundwater bodies, i.e., EC, SO 4 2-, Cl -, Na + and Fe 2+ .…”

“…Studies (Backman et al, 1998) using the contamination index show that the water-quality parameters reflect the influence both of natural and anthropogenic environmental factors on groundwater quality. The authors of the latest research (Knopek and Dąbrowska, 2021) using this index state that the use of this measure to assess the vulnerability of groundwater to pollution is correct, although this indicator in compared to the Landfill Water Pollution Index is more sensitive to changes in the background value for described by them landfill. The authors of this article obtained the index value exceeding 1400.…”

Aim of the study. Landfilling is an activity, which may threaten the destruction or contamination of the soil and water environment. Pollution can be generated both by leachate and by landfill gas. Legal conditions impose on landfill managers to monitor groundwater around the landfills. The impacted soils and groundwater show high chlorides, sulphates, heavy metal concentrations especially as compared to natural hydrochemical background values. Monitoring results can be analyzed using pollution indicators. The objective of this study was to determine the quality of groundwater in a landfill in Wojkowice (southern Poland) using the Backman index. Material and methods. The novelty of the paper results from the use of a different range of parameters than initially included in the formula. The results of water quality monitoring for three piezometers from 2013–2020 were considered. The contamination index was calculated separately for each of the analysed water samples, taking into account the electrolytic conductivity and the concentration of total organic carbon (TOC), Cd, Pb, Zn, Cu, Cr and the sum of N-NO3, N-NO2 and N-NH4. Results and conclusions. The Backman index values range in the groundwater samples were –5.3 to 603. The value of the Backman index increases with the increase in the concentration of individual parameters in groundwater. In the case of heavily transformed areas, the water pollution index has high values, exceeding 3. The results of this index indicated that the quality of the groundwater around the landfill is bad. In the future, it is planned to expand the range of parameters for calculating the index.

Transmission of leachate from municipal solid waste landfills can potentially threaten ecosystems and human societies when the landfill has no system for collecting and treating leachate. Leachate produced from landfills finds its way through the soil to groundwater and surrounding surface waters, leading to pollution of water resources. This study aimed to investigate the effects of leachate from Khalkhal landfill (a city in Ardabil province, northwestern Iran) on the quality of groundwater and surrounding surface water. During 2019-2020, 4 wells (one control well located upstream of the landfill and three wells located downstream of the landfill) and two stations of the surface water resource of the Herochai river were spots for sampling. First, we did sampling during high and low rainfall seasons in accordance with the standards. Second, we analyzed the values of some physical, chemical, and biological quality parameters according to standard methods. The sampling of the soil texture was conducted following ASTM D 422 standards. Then, the soil was analyzed at Reference Laboratory of Water, Soil, and Plant in Ardabil province. The value of most parameters measured in the water of downstream wells was lower than the limit recommended by the Iranian and World Health Organization, indicating no limitation for drinking and agricultural uses. The quality of the Herochai river water was also relatively undesirable in terms of turbidity and total coliform in some samples. Additionally, consistent with the study results, no difference was observed between high and low rainfall seasons. According to the results obtained from different parameters, Schuler and Wilcox diagrams, and landfill water pollution index (LWPI), the quality of upstream and downstream water resources of Khalkhal municipal solid waste landfill was not much different. In other words, the landfill did not affect water.

“…These ordinances focus mostly on the provisions concerning testing for specific electrical conductivity (EC), pH, total organic carbon (TOC), copper, zinc, lead, mercury, cadmium, chromium, and total polycyclic aromatic hydrocarbons. However, in the case of many landfills, some of these elements -such as mercury or chrome -are found in concentrations below the limit of quantification (Wdowczyk and Szymańska-Pulikowska, 2020;Knopek and Dąbrowska, 2021). Therefore, increasing attention is paid to other parameters that are typical indicators of groundwater pollution in the hazard area (Slack et al, 2007).…”

Aim of the study: Groundwater quality monitoring tests in the area of pollution sources are one of the elements of the assessment of groundwater vulnerability. The aim of the article is to indicate a good index for the assessment of water quality and the selection of an appropriate value of the hydrochemical background. Material and methods: The quality of groundwater in the region of the municipal landfills in Dabrowa Gornicza (southern Poland) was assessed in the context of the content of ammonium, chlorides, sulphates, iron and electric conductivity values . The level of the contamination of groundwater was determined on the basis of the monitoring data from 2016-2020. The research used the Landfill Water Pollution Index (LWPI) and the Nemerow index (NI). In order to determine the reliability of the methods used, three different values of the hydrochemical background were taken into account. Results and conclusions: The results of the analyses show that the values of the Nemerow index are definitely higher than the LWPI index. Additionally, the highest values of the indicators were obtained when comparing the obtained results to the hydrochemical background from the 1980s. The maximum values of the indicators were approx. 156 (LWPI) and approx. 721 (NI) for the PZ4 piezometer located east of the landfills. The differentiated results of the index values depending on the selection of the background value and the assignment of individual weights indicate that for such a transformed area it is difficult to indicate the value of the hydrochemical background for which the index values would be representative.
